Young at heart and online? Subjective age and internet use in two Swiss survey studies

Subjective age (SA) indicates how old a person feels. SA has been found to be a marker of an individual’s physical and psychological functioning and openness for new aging experiences. Thus, it can be generally considered as beneficial in promoting healthy aging. We hypothesized that the younger a person feels, the more likely he or she will use the Internet. We evaluated two secondary analyses based on two cross-sectional and representative telephone surveys of 1790 participants (n = 1299, age ≥ 70 years; n = 491, age ≥ 65 years) in Switzerland. Univariate and multivariate analyses, controlled for a number of relevant confounders, confirmed the relationship between lowered SA and heightened Internet use. Given that we were able to analyze two relatively large and representative data sets, we regard our findings, although based on cross-sectional studies, as rather robust. Longitudinal research is required to examine the causal direction of this relationship
